<h3 id="什么是-DevOps"><a href="#什么是-DevOps" class="headerlink" title="什么是 DevOps"></a>什么是 DevOps</h3><p><em>自从 2019 年 DevOps 一词出现以来，其所覆盖的内容在各方专业人士的解读和分析中变得越来越广泛. 在各种讨论和文献中，大量的知识内容( 有些是新出现的，有些是原有的 )被认为和 DevOps 有关，这会让 DevOps 的实践者非常困惑. DevOps 迄今为止还没有得到广泛公认的定义以及确定的知识内容. 接下来就让我们通过 DevOps 的发展渊源来逐渐了解它吧~</em></p>
<h3 id="DevOps-发展渊源"><a href="#DevOps-发展渊源" class="headerlink" title="DevOps 发展渊源"></a>DevOps 发展渊源</h3><p><em>DevOps是敏捷开发的延续，它将敏捷的精神延伸至运维( Operation )阶段. 敏捷开发的主要目的是响应变化，快速交付价值. 以 2001 年的 <code>敏捷宣言</code> 发布这个里程碑为起点，开始几年内企业主要在软件的开发阶段推行敏捷，并没有覆盖到软件的运维阶段. 随着互联网的不断发展，市场变化越来越快，2007年之后软件工程领域出现了新的变化，DevOps星星之火便开始出现~</em></p>

<p><em>Prtrick 在网上看到这个演讲后非常激动，受到大会的启发，他在比利时也发起了名为 DevOpsDays 的自己的会议，最后大会出奇地成功，以至于大家在 Twitter 上的讨论热情不减. <code>受限于 Twitter 上字符的长度，为了精简，大家就把 Twitter 上的话题 #DevOpsDays 简写成了 #DevOps 了，于是 DevOps 一词便在社区中慢慢确定了.</code></em></p>

<h3 id="DevOps-应用与研究现状"><a href="#DevOps-应用与研究现状" class="headerlink" title="DevOps 应用与研究现状"></a>DevOps 应用与研究现状</h3><p><em>目前针对 DevOps 的研究主要集中在微服务、持续集成与储蓄部署、自动化工具的研发等几个方面</em></p>

<p>📖 以上内容摘自书籍 <code>《DevOps 原理、方法与实践》· 荣国平 张贺 邵栋 等编著</code>. 本人强烈向初学者推荐此书 : 本书是目前国内( 也可能是国际范围内 )第一本 DevOps 的系统教材. 同时也是一本不可多得的软件工程教材，既适合软件工程及相关专业的学生学习，也有助于软件企业技术人员阅读. 相信各位读完此书一定会获益匪浅~</p>
